Transient sacroiliac joint-related pain is a common problem following lumbar decompressive surgery without instrumentation.

Objective: Patients with lumbar stenosis profit substantially from decompressive surgery. The change of body position and walking behaviour after successful surgery might lead to changed force effects on the entire spine and on the sacroiliac joint (SIJ). We analyzed the incidence of postoperative SIJ-related pain.

Navigation of total knee arthroplasty: rotation of components and clinical results in a prospectively randomized study.

Background: Navigation was introduced into total knee arthroplasty (TKA) to improve accuracy of component position, function and survival of implants. This study was designed to assess the outcome of navigated TKA in comparison with conventional implantation with the focus on rotational component position and clinical mid-term results.

Methods: In a prospectively randomized single-blinded approach, 90 patients with primary gonarthrosis were assigned to three different groups.

Human bone marrow as a source to generate CMV-specific CD4+ T cells with multifunctional capacity.

The bone marrow (BM) is an important compartment for T cell memory. In cytomegalovirus (CMV)-seropositive individuals peripheral blood (PB) CMV-specific T cells constitute a large fraction of PB T cells but are mostly differentiated effector/effector memory T cells with limited survival and proliferative potential. In this study, we performed a comprehensive analysis of the CMV-specific T cell response in BM studying both CD4+ and CD8+ T cell responses against overlapping peptide pools of the CMV proteins pp65 and immediate early protein-1.

Integrated outcome assessment after anterior cervical discectomy and fusion: myelocompression but not adjacent instability affect patient-reported quality of life and cervical spine symptoms.

Study Design: The authors conducted a cross-sectional study.

Objective: Integrated assessment of adjacent instability (AI), myelocompression (MC), magnetic resonance imaging (MRI) signs of myelopathy (MRISM), physician-assessed clinical signs and symptoms, including clinical signs of myelopathy (CSM), patients' self-reported symptoms and quality of life after anterior cervical discectomy and fusion (ACDF).

Materials And Methods: Fifty-four patients who had ACDF between 1986 and 1995 received MRI scans, conventional and flexion/extension radiographs to assess myelocompression, MRISM, fusion, and AI.
